engine painting

[SHOtype]

I am currently trying to paint all the little plastic pieces in the engine bay on my roomates SHO but I keep getting fisheyes no matter what type of paint I use or how light I put it on. I cleaned them sanded the heck out of them and cleaned them again.

Detergent
cheese cloth
LIGHT COAT oof primer (preferably some kind of NAPA rattle can paint)
light sand
cheese cloth
another light coat oof primer
very light sand
light coat finish paint (NAPA preferably)
very, very light sand
cheese cloth
finish coat (again, NAPA)


I dont know why, but NAPA paint is the bomb when it comes to rattle can paint. I have painted many engines, grease and all, and they rairly fisheye.

The first coat if primer is very important. that is why you need to use a diluted mix of detergent to thoroughly clean the plastic prior to painting.

hope it helps thumb

I sandblasted all the stuff that I painted in the engine bay, no bubling paint for me. thumb

Thanks I am going to try the sandblasting first since I have access to one and that sounds the easyiest of the two. But I will try the NAPA brand paint.

FLAT paint has worked well for me.Don't use the HI-TEMP clear from Autozone.It yellows without any heat on it at all.Painted my intake white and cleared with that stuff.Have to redo it all cause of the damn stuff headbang

I agree with fred, i use berrymans to remove all the grease, oil and misc. crap. Then i wash the parts with dish soap and hot water, works fine for me.

use wax and grease remover before sanding... then sand the parts and wash them then use wax and grease remover again. If you still get fish eyes then check the paint, and make sure the part doesn't have any grease on it (like from tire shine like most car washes love to use)... you may have to bake the part since it's plastic to release some of the oils (if you don't do this the paint may peal later if it doesn't fish eye)


Problems like that are why I do paint work any more metal is much easier to work with!
